What is the most meaningful book you have ever read?

As a fan of online literature, I haven't actually read any novels, but I can answer your question based on what I have learned about online literature. Generally speaking, we can consider a meaningful book from the following aspects: 1. Plot: A good novel should have an attractive plot, a thrilling plot twist, and a plot arrangement with climaxes that make the reader immersed in it and unable to extricate themselves. 2. Character image: A good novel should create distinct and three-dimensional characters so that readers can feel the character's personality, thoughts, emotions, and actions and resonate with them. 3. Thematic thoughts: A good novel should have a profound theme that can trigger the reader's thinking and reflection, enlighten the reader's soul, and improve the reader's quality. In my learning process, I have learned that some classic novels such as "Dream of the Red Chamber","Journey to the West","Water Margins" and so on, these novels have very wonderful story plots and characters, and contain a profound theme, which is very helpful to improve my reading ability and thinking ability.
